## Multiple authentication schemes in the API Explorer

The API Explorer now supports multiple authentication schemes and combinations of authentication schemes for OpenAPI specs.

First, configure your OpenAPI spec with multiple security options:

```yaml openapi.yml {8-11}
/plant/search/status:
  get:
    tags:
      - plant
    summary: Search plants by status
    description: Filter plants based on their current status.
    operationId: searchPlantsByStatus
    security:
      - bearerAuth: []  # Option 1: Bearer token only (OR)
      - basicAuth: []   # Option 2: Basic auth AND API key (combined)
        apiKey: []
```

Then, the API Explorer automatically displays all available authentication options in a dropdown menu, allowing users to select and configure their preferred authentication method before sending requests.
